(Cl. 15-236) This invention appertains to cutlery, and morehas been illustrated merely to show the method particularly to a novelattachment for a cake of using the attachment. or similar knife. Theknife K embodies the usual knife blade 5 One of the primary objects ofmy invention and manipulating handle 6. The attachment A 5 is to providea device which can be readily comprises a body formed from a singleblank 5 slipped on the blade of a knife and reciprocated of sheet metal,and this body includes spaced, longitudinally thereof for effectivelyclearing the substantially parallel side walls I, and a conblade ofcrumbs and the like adhering thereto necting top Wall 8. The side andtop walls have after the slicing of cakes or other confections or formedthereon an outside peripheral reinforcpastries. ing flange 9.

1. An attachment for cleaning knife blades comprising a body includingspaced parallel side walls, a connecting top wall, the body beingadapted to straddle a knife blade, and forwardly and inwardly extendingresilient wings, said wings having cleaning edges normally urged towardone another and into intimate contact simultaneously with the oppositefaces of the knife blade by the inherent resiliency of said wings.

2. An attachment for cleaning knife blades comprising a body includingspaced parallel side walls, a connecting top wall, forwardly andinwardly extending resilient wings, the body being adapted to straddle aknife blade, said wings having cleaning edges normally urged toward oneanother and into contact simultaneously with the opposite faces of theknife blade by the inherent resiliency of said wings, and outwardlyflaring guiding lips formed on the forward lower corners of said wings.

3. An attachment for cleaning knife blades comprising a body includingspaced side walls and a connecting top wall, said body being adapted tostraddle a knife blade, forwardly and inwardly extending resilient wingson the side walls, said wings having cleaning edges for simultaneouslyengaging the opposite faces of the knife blade, and outwardly extendinghandles on the side walls.

4. An attachment for cleaning knife blades comprising a body including apair of spaced side walls and a connecting top wall, the body beingadapted to straddle a knife blade, an outwardly extending reinforcingflange on the side and top walls, inwardly projecting resilient cleaningwings on the side walls for simultaneously engaging the opposite facesof the knife blade, outwardly diverging guide lips on the lower forwardcorners of the wings, outwardly projecting ears on the flange on saidside walls, and handles secured to said ears.
